ABSTRACT:
The specification discloses an insert for lining and/or relining valve guides for reciprocating-type poppet valves in cylinder heads of internal combustion engines. The insert has multiple layers of metallic materials and preferably includes an inner sleeve or tube of spring-tempered phosphor bronze and an outer carrier sleeve or tube of steel or aluminum. The combined sleeves provide the insert with high wear resistance and lubricity and excellent heat transfer properties. Separate formation and later assembly allows precise control of wall thicknesses, diameters and concentricities.
Also disclosed is a method for manufacturing the insert including separately forming the inner and outer sleeves or tubes, and inserting one within the other for frictionally holding them together.
